Description
Technical field
The present invention relates to drilling fluid materials and its production technology field, refer specifically to a kind of drilling fluid silicon oil foam killer and its
Production technology.
Background technology
During the mine of the energy such as oil, natural gas is drilled, the gas in stratum easily invades drilling fluid so that boring
Well liquid is blistered, and at the same time, added to materials such as the surfactant in drilling fluid, lubricants drilling fluid may also be caused to rise
Bubble, these foams can reduce carrying capacity and proportion of the drilling fluid for landwaste, trigger the accidents such as cave-in, bit freezing.Pin
To this problem, using it is most be that defoamer is added in drilling fluid, to reduce the foam in drilling fluid.At present, defoamer
It is broadly divided into organic silicon type, polyether-type and non-silicon type three major types.Wherein, power is strong, resistance to height because it is defoamed for organic silicon type defoamer
It is warm, non-volatile, nontoxic, chemical property is stable, insoluble in frothing media the advantages that and be widely used.However, existing drilling fluid
Following technical problem is still suffered from defoamer：
（1）Easily condensed under low temperature, poor fluidity, it is difficult to applied to low temperature environment；
（2）Heat endurance is poor, and evaporation loss is big under hot conditions, seriously affects its defoaming capacity；
（3）It is poor to defoam continuation, antifoam performance is typically only capable to maintain a few minutes, it is necessary to defoaming continuously be added, to drilling well
Production causes cost burden；
（4）Dosage is big, pollution is big, and when use is also easy to produce cohesion, scum silica frost phenomenon, causes mud contamination.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of be respectively provided with low temperature or hot conditions excellent fluidity,
Dosage is small and with the drilling fluid silicon oil foam killer and its production technology for continuing antifoam performance.
To solve the above problems, a kind of drilling fluid silicon oil foam killer of the present invention, its raw material components and each component
Parts by weight be：1100-1400 parts of kerosene, 100-200 parts of aluminum stearate, 100-200 parts of emulsifying agent, methyl-silicone oil
50-150 parts, 100-300 parts of tributyl phosphate, 100-200 parts of n-octyl alcohol, 50-200 parts of water；The drilling fluid silicone oil
The production technology of defoamer, comprises the following steps：
（1）It is placed according to formula each raw material components of precise spare in corresponding container；
（2）Reaction kettle and turn on agitator are opened, the load weighted kerosene, aluminum stearate are uniformly slowly added into described
In reaction kettle, it is 30-50 DEG C to keep temperature in the kettle, is slowly homogeneously added into the emulsifying agent in kettle in 30-50 minutes；
Lasting stirring heating, after temperature is increased to 90-100 DEG C, persistently keeps the temperature 120-180 minutes；
（3）After insulation, when temperature in the kettle is reduced to 55-65 DEG C, by the methyl-silicone oil, tributyl phosphate, just pungent
Alcohol, water are added into the reaction kettle, persistently stir and keep the temperature 40-60 minutes it is fully emulsified；
（4）After emulsification, treat that temperature in the kettle is reduced to 40-50 DEG C, product in kettle is transferred in storage container, sampling inspection
Test and be incorporated to stock and put.
Further, the parts by weight of each component are：1200-1300 parts of kerosene, 120-160 parts of aluminum stearate, breast
120-160 parts of agent, 60-120 parts of methyl-silicone oil, 160-240 parts of tributyl phosphate, 100-160 parts of n-octyl alcohol, water 80-
150 parts.
Further, the parts by weight of each component are：1260-1300 parts of kerosene, 140-160 parts of aluminum stearate, breast
140-160 parts of agent, 80-100 parts of methyl-silicone oil, 180-200 parts of tributyl phosphate, 120-150 parts of n-octyl alcohol, water
100-120 parts.
Further, the emulsifying agent is SP-40（Arlacel-40）、SP-60（Arlacel-60）、SP-80（Arlacel-80）In extremely
A kind of few and T-60（Tween-60）And/or polyoxethylene octylphenyl phenol ether（OP-10）Mixture.
The present invention has the following advantages compared with prior art：
